Description

The invention relates to a method for displaying patient data and to an associated control unit, wherein the patient data are present or stored in a data format with at least two parts.

Background of the invention

In the medical field, a so-called client-server architecture predominates for the processing, presentation and storage of medical data. This means that records are often shared between users, i. a client (machine), and a server, i. a central unit or a so-called cloud, back and forth. If adjustments are made to the data on the client side, it often takes a lot of time and resources to retrieve the data from the server to the client and vice versa.

When creating a patient list, various IT systems are usually involved. The servers each have specific tasks to take processing load from the local computers (so-called rich clients). A database server supplies the application server with data that is usually structured in a list or in a table. The presentation server provides the application server with general presentation logic, usually based on a repository of displayable UI elements. The application server supplies the client computer with applications that provide certain functionalities. However, it is also customary to shift part of the processing and presentation load to the rich client in modern user interfaces or user interfaces (UIs). The servers are designed for the total load of a hospital, the rich clients usually have common and common equipment in the hospital.

In the hospital, it is now essential to retrieve the best possible performance or performance from the system. This depends very much on factors that can not be influenced (network load, network performance and server hardware, etc.). However, performance improves if the computing power of the rich client in particular is cleverly organized and used.

In 1 schematically shows a processing stack for displaying a graphically edited patient list. First, the data PD are retrieved to the patient from the database server or application server S and provided in list form L the rich client RC. The rich client then calculates the graphical representation of the patient list on the user interface UI using its arithmetic unit RE, which has one or more CPUs and / or one or more GPUs.

The performance is perceived by the user over time, in which he can not operate the user interface UI. This "waiting time" is calculated from the number of patients multiplied by the processing time of the UI elements per patient added to the display frame functionality.

In the context of a time- and resource-optimized representation of medical image data, which often include large amounts of data, various charging strategies are known.

For example, it is off EP 2648122 A1 an image data type specific charging strategy and off DE 10 2010 010 195 A1 a method for preprocessing and storing image attributes for the accelerated display of medical images in medical applications known. These image data are generally stored in a specific data format according to the DICOM standard (Digital Imaging and Communication in Medicine) which is commonly used in medical technology, so that the relevant information for loading the regions of the image data to be detected can often be read out from the metadata. Patient data, however, usually consists of different data formats because, as explained above, they are created using different IT systems. They are usually in list form or in a tabular form, wherein the rows or columns of such a table can each represent a list element of a list. Thus, the known image data representation methods can not be applied to patient data. Rather, the patient data should be offered to the user virtually "in one piece", whereby a waiting time of a maximum of three seconds is reasonable for the user.

It is an object of the invention to ensure a fast patient data presentation on the client, which can be performed as quickly as possible and with little resource consumption.

Presentation of the invention

This object is solved by the independent claims. Advantageous developments are the subject of the dependent claims.

The invention claims a method for displaying patient data (PD), wherein the patient data are present in a data format with at least two parts or are structured,
having the following steps:

• a) wherein in a first step at a user interface a first part of the patient data is prepared by a computing unit and displayed on the user interface,
• b) in a further step, at least one further part of the patient data is processed by a computing unit and displayed on the user interface,
• c) wherein the order of the reprocessing parts of the patient data is predefined on the basis of a charging strategy by a control unit upstream of the arithmetic unit, and
• d) the control unit with the help of the charging strategy, the period between the preparation in step a) and the processing in step b) of the arithmetic unit releases, so that the arithmetic unit additional computing time for other processing is available.

• – Mittel zur Speicherung einer Ladestrategie, die die Reihenfolge der aufzubereitenden Teile der Patientendaten vorgibt, und
• – Mittel zur Freigabe des Zeitraums zwischen einer ersten Aufbereitung eines ersten Teils der Patientendaten und einer weiteren Aufbereitung eines weiteren Teils der Patientendaten an die Recheneinheit, damit der Recheneinheit zusätzlich Rechenzeit für eine andere Verarbeitung zur Verfügung stehen kann.

A further aspect of the invention is a control unit for a client computer, which is preceded by a computing unit for processing patient data that is present in a data format with at least two parts, comprising:

• - means for storing a charging strategy, which specifies the order of the parts of the patient data to be reprocessed, and
• - Means for releasing the period between a first preparation of a first part of the patient data and a further processing of another part of the patient data to the arithmetic unit, so that the arithmetic unit can be additional computing time for another processing available.

The control unit has, in particular, means or modules for carrying out the method, which may each be hardware-based and / or firmware-based and / or software-based or computer programs.

The method may be implemented in the form of program code on a client computer or a server (computer).

The control unit and computer programs, like the method, can be trained accordingly.

The invention has the following advantages:

By means of the invention, the structure of the data loading is structured so that the remaining computing time of the CPU / GPU is used for further processing or further tasks.

The procedure described above subjects the user to downloading the patient data in smaller parts and then reloading the parts or elements from the list bit by bit. If the user has received sufficient information regarding the patient's data, he may also stop or pause the loading process before all the information has been completely reloaded. This improves system performance, especially the user "felt" wait time.

embodiments

Further advantages, details and developments of the invention will become apparent from the following description of embodiments in conjunction with the drawings. Show it:

1 the initially explained schematic arrangement,

2 a possible embodiment of the invention.

The 2 has essentially the same components or elements as 1 on. The UI is preceded by a control unit, for example in the form of a dispatcher D, which has the task of interlinking the display logic and processing logic in a complex IT system in such a way that the perceived system performance is improved for the user. The patient data is usually presented in several parts contiguous to the rich client RC. They can be present or stored in a list L with the list of patient elements, for example 1 to 4, on the rich client. There may also be more than the four list elements shown. The distributor D accesses the first list element of the list L eg 1 for processing by the arithmetic unit RE on the basis of a predefined charging strategy, this being displayed after the processing on the user interface UI. After the preparation of the first list element, the distributor D releases the time period until the preparation of a next list element, for example 2, to the arithmetic unit so that it can in the meantime process other tasks, such as user input at the UI. The order of editing the list elements essentially depends on the loading strategy, eg First-In-First-Out (FIFO). Other charging strategies such as last-in-first-out (LIFO) and round robin (RR) are also conceivable. In RR, also called a round-trip method, all processes are granted access to the required resources, eg CPU / GPU computation time, in succession for a short period in each case - a so-called time slot.

The arithmetic unit prepares one list element after the other until all parts or list elements have been processed and / or an abort criterion is fulfilled. Such Abort criterion can be a manual abort of the data preparation by the user or the achievement of the last list element in the list after its preparation.

By controlling the display calculation or processing of the list element in the application, a duration of preparation time of the UI elements per patient added to the display frame functionality is required per patient. Overall, the total time for all patients increases, but the perceived performance of the overall system improves. In the time units between the preparation of the parts of the list or entries of two patient data, the computing power of the rich client is available for other tasks, such as responding to user inputs.

Although the invention has been further illustrated and described in detail by the preferred embodiment, the invention is not limited by the disclosed examples, and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention.
